I am trying to use the WiFiNINA AP_SimpleWebServer example - it states in the header that it is for creating an access point with no password. But the sketch fails unless there is a ssid and password at least 8 characters long - as explained here
Is it possible to create an access point with no password?
I can understand why, you aparently did not read the guidelines otherwise you would given us the information we needed to answer your question. A simple thing like posting your code, which where the problem was, would probably have gotten you an answer in short order.
